Re: pic: Variable Diameter Wheels? In Vex?! - pic 3
I started looking into this same idea last year after a discussion here about variable diameter wheels. Unfortunately the other mentors on my team felt it was beyond our capabilities, so I haven't had the opportunity to test it yet.
As far as making the wheels, my plan was to make a wheel model out of clay, then create a rubber mold and use liquid casting plastic for the wheels, with a section of axle embedded in the plastic. For the surface, wedge shaped sections of conveyor belting (the same type currently used by many teams) could be attached to the surface.
